- (In)congruent scenes: eye movements and language productionPublication . Monteiro, Paula; Costa, Armanda; Carvalho, Mário; Baptista, AdrianaIn this study we want to know how visual and semantic properties of scenes determine linguistic production. We prepared an experiment with two factors: scene type (photograph vs. drawing) and semantic consistency (congruent vs. incongruent), resulting in four experimental conditions. 24 pictures representing natural scenes were created, each one in the four conditions. 24 children (8 y/o), native speakers of European Portuguese, without visual or attentional deficits or language disorders, were given a picture viewing task, followed by 2 questions. Participants ’ eye-movements and linguistic production were recorded with an SMI IVIEW X HI-SPEED system and with a Logitech® Webcam Pro 9000. First fixation, fixation duration and gaze were taken from two AoI (heads and (in)congruent objet). Produced speech was computerized with TEITOK and measures of fluency and linguistic complexity were extracted. Preliminary results show a main effect of scene type on first fixation (p=0,010), and of scene congruency on gaze (p=0,006). Scene type and congruency also impact on fluency and on production of Nouns referring represented or inferred entities: 60% of words in response to photographs; 53% Nouns to incongruent photos. As expected, results show a relationship between visual scene properties and congruency, and visual behavior and produced speech.
- Parâmetros para análise de narrativas orais em crianças com e sem perturbação da linguagem expressivaPublication . Monteiro, Paula; Costa, Armanda; Baptista, AdrianaAnalysis of children’s productions of oral narratives is a highly effective research tool that allows examiners to document children’s productive vocabulary and grammar (using microstructural analyses) as well as children’s text level narrative organization skills (using macrostructural analyses). In this study we used the Narrative Scoring Scheme and the Speech Rate and Fluency in Children and Adolescents to analyse the productions of oral narratives of children with and without language disorders. The results showed language developmental effects. Children with language disorders have difficulties in the use of macro and microstructural features and lower speech fluency score.
